Medicare allowed an average of $14.28 per service and paid $14.28 of that, the balance being the patient's coinsurance and deductible (2024 data). Providers submitted an average of $71.42, which is what they billed rather than what they received — Medicare pays its fee schedule regardless of the charge.

Does 84134 pay differently in an office than a hospital?

Clinical Laboratory, with 125,843 services from 262 clinicians. Next are Internal Medicine, Nurse Practitioner, Hematology-Oncology.

Balance is patient coinsurance

Providers submitted an average of $71.42 for this code and Medicare allowed $14.28 — 5.0× less. That gap is normal and means nothing on its own: Medicare pays its fee schedule regardless of what is billed, so the submitted figure describes a hospital chargemaster, not a price anyone paid. Of the allowed amount Medicare paid $14.28 (100%); the rest is the patient’s coinsurance and deductible.

Office pays differently to hospital

Office / non-facility: $14.28
Hospital / facility: $14.30

The facility rate is higher for this code, which is unusual and generally means the service depends on equipment or staffing a hospital carries. 132,768 services were billed in an office setting and 481 in a facility.

What Medicare pays for CPT 84134

Across 133,249 services billed by 305 providers to 92,537 beneficiaries, Medicare allowed an average of $14.28 per service. That is 1.4 services per beneficiary, so this is a code patients typically receive more than once. The allowed amount is the figure that matters: it is what Medicare and the patient together owe, set by the fee schedule and adjusted for local practice costs. What a provider chose to submit has no bearing on it.

84134 reimbursement by state

Two different numbers. Allowed is what Medicare actually allowed in that state, which includes the local practice-cost adjustment. Standardized strips that geographic adjustment out of the payment, so it is the column to use when comparing states — a difference there reflects how the code was billed, not what it costs to run a practice locally.

Billing this code is not the same as earning it

An allowed amount is revenue to a practice, not income to a clinician. It funds staff, premises, equipment and supplies before anyone is paid. What clinicians actually earn is published separately by the Department of Labor, and what industry pays them is published separately again by CMS — this site carries both.

Where this comes from. CMS Medicare Physician & Other Practitioners, by Provider and Service, 2024. It covers fee-for-service Original Medicare Part B only — not Medicare Advantage, not Medicaid, and not commercial insurance, which typically pays more for the same code.

How it is averaged. CMS publishes one average per provider per code. Every figure here is re-weighted by the number of services, so a clinician who billed the code 4,000 times counts 4,000 times more than one who billed it twice. CMS also suppresses any provider-code pair with fewer than 11 beneficiaries, so low-volume practice is missing from these totals by design.
